NGK Spark Plug BR8ES SOLID (3961) — Standard Resistor, Solid Terminal, Pack Pricing (per plug, min 10)

NGK BR8ES SOLID (part 3961) is a standard resistor spark plug designed for reliable ignition performance in compatible gasoline engines.

Before ordering, confirm this NGK 3961 fits your vehicle—this listing notes purchase rules: plugs are priced individually, sold in multiples of 10, and require a minimum order of 10. The BR8ES SOLID is a solid terminal, resistor-type spark plug built to OEM-style dimensions and basic durability for everyday driving and routine maintenance.

What are the core characteristics of the NGK BR8ES SOLID spark plug?

This NGK unit is a conventional resistor spark plug with a solid terminal nut and standard center electrode design. It provides predictable starting and stable combustion in engines that specify a BR8ES-equivalent part.

• NGK part number: 3961 (BR8ES SOLID)
• Plug type: Resistor with solid terminal nut
• Fit: Universal/OEM-equivalent dimensions for specified applications
• Sold individually but packaged and ordered in increments of 10

How does ordering and packaging work for this NGK plug?

This listing shows a per-plug price, however the seller enforces bulk ordering: a minimum of 10 plugs must be ordered and sales are processed in multiples of 10. Ensure you select the correct quantity and verify vehicle fitment before checkout.

• Priced per plug but sold in packs of 10 units
• Minimum purchase quantity: 10 plugs
• Check your vehicle’s service manual or parts lookup for BR8ES/3961 compatibility

Why choose this NGK standard resistor model over other plug types?

Standard resistor plugs like the BR8ES deliver interference suppression and consistent spark performance for many OEM ignition systems without the cost or installation differences of iridium/titanium types. They are a practical option for routine replacement where OEM specifies a standard plug.

• Resistor construction helps reduce radio and electronic interference
• Solid terminal nut matches many factory ignition wire connectors
• Cost-effective replacement for routine maintenance

What design features help reliability and prevent faults?

NGK engineering includes features to reduce common ignition issues: corrugated insulator ribs help prevent flashover and cold-rolled threads reduce risk of cylinder head damage during installation. These basic protections support safe, repeatable service life.

• Corrugated ribs on the insulator to resist flashover
• Cold-rolled threads to minimize galling and thread damage
• Standard electrode profile for predictable gap and spark location

Who is this for? The NGK 3961 BR8ES SOLID spark plug is intended for vehicle owners, mechanics, and fleet managers looking for an OEM-style, cost-efficient replacement plug specified as BR8ES. It suits applications where a resistor plug with a solid terminal is required and buyers are prepared to order in the minimum commercial quantity of ten. If your engine’s parts list names BR8ES or NGK 3961, this plug provides a straightforward, reliable substitute for routine tune-ups and service intervals.
